Nobody knows if there are significant long-term (beyond 10 years) adverse effects from LASIK. However, the scientific community does not foresee any significant long-term adverse effects. The flap-making technology has been available since the late 1940's. The excimer laser has been available since the early 1980's. Neither have shown long-term problems so it is unlikely their combined use in LASIK will cause long-term problems. Eye doctors have tremendous confidence in the procedure.

LASIK surgery has been performed since 1991 in Europe, and is based on another vision correction technique that has been used for more than 40 years. For many years, various clinical studies have been performed and each has failed to demonstrate any long-term harmful effects on the cornea. See similar questions...

The wavelength used by the Virulite device is very close to that of the Nd:YAG laser which has been used by doctors all over the world for several decades. The Virulite Cold Sore Machine radiates divergent light which is inherently 'eye-safe' and uses powers 1/10'000 less than medical lasers already in use. It has been documented in medical papers that Nd:YAG laser surgery to a pregnant woman's cervix (neck of the womb) is a safe procedure if clinically indicated. See similar questions...

Topical therapy results in such minimal levels of medication in the bloodstream, if any, that there is virtually no risk of systemic side effects except allergic reactions. Possible side effects associated with oral antibiotic therapy include upset stomach, sensitivity to sun exposure, tooth discoloration, diarrhea, allergic reactions and vaginal yeast infections.

There are side effects to these medications but usually they are not long term. Most of them are somewhat bothersome but very few of them are dangerous. There are more problems with untreated emotional problems than problems from side effects. See similar questions...

Two of the most common side effects are dry eye and seeing starbursts or halos around lights at nighttime, both which are usually temporary and disappear with time as the eyes heal. Dry eye can be soothed with the use of artificial tears which soothes the eye by keeping it moist. Less than 1% of LASIK patients have vision that worsens rather than improves.

Yes. Studies on both humans and animals have proven that regular use of ecstasy produces long-lasting, perhaps permanent damage to the brain's ability to think and store memories. See similar questions...

The most serious complication long-term complication of LASIK surgery has been keratectasia. Keratectasia is progressive thinning and distortion of the cornea resulting in anthing from mild to severe astigmatism. This can occur when the early stages of "conical cornea" or keratoconus are not detected prior to surgery. The Orbscan II at Fendalton Eye Clinic is the most sensitive method currently available for detection of early keratoconus or subtle abnormalities of the cornea. See similar questions...

The long term effects of crack affect the user physically, mentally, and emotionally. An individual's long term effects from crack vary from person to person depending on their length and intensity of abuse. In general, the long term effects of crack include restlessness, mood change, irritability, auditory hallucinations, extreme paranoia, and eventually and rather quickly, addiction.

The long-term effects of preventing acid secretion with proton pump inhibitors (PPIs) are not known, as PPIs have only been available for the last decade. However, most doctors believe them to be safe. H2 inhibitors (or blockers), such as Pepcid® AC , have been around for nearly 30 years. See similar questions...

Skin cancer. Some people are at a higher risk than the normal population for developing skin cancer, including people who have had previous non-melanoma skin cancer, arsenic therapy or X-ray therapy to the skin, as well as individuals with extremely light complexions which always burn and never tan. In general, these patients are not considered for PUVA therapy unless strong extenuating circumstances exist in favor of it. See similar questions...

Although LASIK and PRK is a relatively new procedures, results from U.S. studies to date show that 95-98% of patients with mild to moderate myopia who have undergone PRK have achieved stable 20/40 distance vision or better with one treatment. Although a 1-2% of eyes will lose a line of best correctable vision, no significant long-term sight threatening consequences have been reported in ten year follow-up from international centers.

There is no reliable study to support the claim that infertility treatment causes ovarian cancer. One highly publicized study suggested a link between ovarian cancer in women who had received ovulation induction drugs. These women were also infertile and infertile women are at greater risk for ovarian cancer whether or not they receive ovulation induction drugs. It was not possible to determine if the increased risk was due to the women's infertility or drug treatment. See similar questions...
